That's not really what FPGAs are good for. Unless you are using a really high-end FPGA (read: >$10,000/unit), the raw compute power is not going to beat a decent gaming GPU. The benefit of FPGAs is that you get very precise timing control, which makes then very good for software-defined IO and other latency-sensitive hard real-time applications.
